This is a flashlight I obtained a while back when I was into airsoft. It can be attached to guns with rails, such as Glocks. I don't really remember using it much, as I've never participated in night games. Regarding whether it's a real item or a replica, I recall it being the same type used in actual service, sold to the public. Since it's from a time before high-intensity LEDs, the bulb could burn out. I've confirmed that it still lights up for now. It requires two CR123A batteries to operate. Please note that the CR123A batteries in the photos are for testing purposes and are not included. Below is an automatically generated description (Honestly, I don't think it's suitable for everyday use): 【High Durability】 The M-3 Tactical Illuminator is designed for use in harsh environments.
